In Google Website Optimizer Essential Training, David Booth shows how to use Website Optimizer, Google's free tool for conversion optimization. Conversion optimization, or landing page testing, is the process of experimenting with content and design alternatives, displaying them to visitors, and comparing the results, with the goal of improving site performance in regard to marketing, sales, or other conversion metrics. The course covers theory and best practices, as well as a real-world implementation of A/B and multivariate testing. Practical techniques for identifying areas for improvement, estimating sample size, choosing an experiment type, designing, launching, and validating an experiment, and analyzing Website Optimizer reports are included.
